Are there any recommendations on how to decide, whether the receive callback function should re-initiate a receive operation after a receive error or not?

Unlike TCP, UDP does not establish a connection. By default you will not receive any network errors on a UDP socket. You have to call connect() on the socket in order to receive (ICMP) error messages, but this has other implications. With UDP it is more common to rely on application layer error messages and/or timeouts.
